Model: FP5
Android version: 15
Build number: FP5.VT2P.C.089.20260311
Issue/Unexpected behaviour:
Since the update to the current build (about 3 weeks ago) my FP5 often begins using Mobile data, while keeping an active but then unused WLAN connection with the Status “Low quality” (“Niedrige Qualität” if set to german).
If I disable Mobile data the WLAN connection is stable and works fine, as soon as I then enable Mobile data again, the issue imidiately occurs again.
The FP5 has never recoverd from this bad state, without me moving it to anoter location or disabling WLAN waiting several seconds and then reenabling it or switching to another SSID.
Other Android devices at the exact same location have a stable and working WLAN connection.
Expected behaviour:
If a “low quality” WLAN connection is detected, I would expect my phone to either roam to a different AP (if available) or to cleanly disconnect from (and eventually reconnect to) WLAN and begin using Mobile data.
Current Settings:
System > Developer options > Mobile data always active = disabled (it was never enabled, but some posts suggested this would cause more aggressive network switching so I include it)
System > Developer options > Enable Wi-Fi verbose logging = enabled (for better insight/debugging)
Locations:
At first I thought the issue was my Home WLAN Setup, because I currently run multiple old 802.11ac (Wi-Fi 5) APs with openWRT and am replacing them with 802.11be (Wi-Fi 7) Unify APs as they fail, but up until now it was stable and Roaming somewhat worked and the low quality issue also occured at other locations by now.
